Bash Version: 5.0
Patch Level: 17
Release Status: release
Description:
BASH completion cannot correctly handle file names containing newline
characters.
Repeat-By:
# First, get a shell with no completion loaded and show it working:
$ bash --norc
bash-5.0$ ls -b
one\ntwo\nthree\nfour\nfive\nsix
bash-5.0$ xxx <TAB>'one
two
three
four
five
six'
bash-5.0$ touch foo
bash-5.0$ xxx <TAB>
foo one^Jtwo^Jthree^Jfour^Jfive^Jsix
bash-5.0$ xxx <TAB>'one
two
three
four
five
six'
# Now, load the completion scripts and watch it break:
bash-5.0$ source /usr/share/bash-completion/bash_completion
bash-5.0$ ls -b
foo one\ntwo\nthree\nfour\nfive\nsix
bash-5.0$ xxx <TAB>
five foo four one six three two
bash-5.0$ xxx o<TAB>
five four one six three two
# The last two completions are garbage.
# The file name is being split on newlines.
